Fifth Eye's Mask

 is an item of equipment in Tyranny.

Background
The Fifth Eye's mask resembles a standard Crimson Spear helmet. Closer inspection reveals that the bronze interior of the mask has been etched with all manner of phrases - secrets, ancient lore, and inarticulate pleas for help. The metal around the mouth opening is much tarnished, suggesting that the Fifth Eye obsessively licked his lips.

Location

 * Carried by Fifth Eye.
 * Two copies can be obtained: The first one can be obtained by killing Fifth Eye in the Ascension hall (either by siding with the rebels, or by siding with chorus and then betraying them). The second copy is obtained if you chose to toss Fifth Eye down from the Spire with the message - he will be standing alive(!) in the yard, but can be looted as a corpse.
